[1.0 Bughunt] If we apply thickness after applying fillet to a padded shape, an error is thrown

[raindropsfromsky]

Is there an existing issue for this?

• I have searched the existing issues

Problem description

1. Create a new sketch.
2. Add any shape (e.g. rectangle)
3. Close the sketch
4. Pad it.
5. Select a face and apply chamfer. Click OK.
6. Now select the same face again (which has chamfer around it), and apply thickness.
7. The result is like this (OK)
   
8. Now repeat the experiment, but in step-5, select Fillet.
9. When thickness is added, an error pops up

4203.01 <App> Document.cpp(3158): Unknown exception in Unnamed#Thickness thrown
Thickness: Unknown exception!

Desired behavior:

1. Fillet should work just like chamfer, without error.

Subproject(s) affected?

None

Anything else?

Probably this error comes because of the angle at the edge of the face:

• A chamfer offers a clear angle
• A fillet is tangent with both faces (zero angle).

Thickness seems to be looking for a sharp angle at the edge. That's why it works with chamfer, but not with fillet.

confirmed. There are a lot of options on thickness. It's possible to trigger other errors with a chamfer if you push it hard enough.
